How does Dacoma Pwa compare with other water systems in Woods County?

Its population served is well below the county average of 772 people per system, and accounts for 1.9% of the 7,723 people reported by systems filed under the county.

What does “community water system” mean?
A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. Homes, apartments and mobile-home parks are served by these. Oklahoma has 864 active community water systems, 69% of the state's 1,254 active systems. Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 67 Oklahoma systems (5.3%) list purchased groundwater as their primary source.
Who owns and regulates Dacoma Pwa?
EPA lists Dacoma Pwa as owned by a local government. The OK state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 7 of the 10 active systems in Woods County (70%) are also owned by a local government.
Does Dacoma Pwa have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in January 2026. The violations listed here began between January 2022 and January 2026. By type: 8 monitoring and reporting, 2 monitoring, 1 required treatment not met and 1 reporting. The contaminant or rule involved most often is Chlorine (3 of them). EPA lists 8 as resolved, 2 as unaddressed and 2 as archived. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
